Yes! they would be your aunt and uncle!
<span>Gasoline contains stored chemical energy. When gasoline is burned in a lawn mower, the energy is transformed into mechanical and thermal energy.</span>
Hydropower can be harnessed from flowing and falling water. Water stored behind dams and at a height has a lot of potential energy which is converted into mechanical and electrical energy.This water is released gradually and is made to fall under the force of gravity and drive hydraulic turbines and electrical generators.
Hydropower is also another indirect form of using solar energy. Hydropower has great potential as a supplier of electricity but environmental constraints limit such a development as the generation of electricity by hydroelectric power plants result in pollution and massive ecological disruptions such as land flooding, siltation, eutrophication and adverse effects on flora and fauna.
Smaller dams and reservoirs cause less damage but cannot exploit the full potential of this energy resource. Planning environmental impact assessment and construction of a hydroelectric power plant takes many years and the high initial capital investments are also limiting factors in the development of hydropower.
The development cost of hydroelectric power plants can be reduced by developing low cost turbines and generators, involving public participation in the development and operation of the project and using efficient environmental friendly technologies.
Explanation:
The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
Answer;
-Sodium
Because Andy has high blood pressure and heart disease, he must lower his intake of Sodium.
Explanation;
-Eating substances rich in sodium such as salt raises the amount of sodium in the bloodstream and wrecks the delicate balance, reducing the ability of the kidneys to remove the water.The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.
-Therefore, for an individual with high blood pressure and heart disease like the case of Andy, he or she must lower the intake of sodium.
